Dahlias chosen to thrive in pots and containers

Dahlias for pots
You do not need a large border to grow dahlias well. Dahlias for pots bring the same long flowering season into patios, terraces, balconies and smaller gardens, where their colour and form can be enjoyed at closer range. Compact and more manageable varieties are especially well suited to containers, giving you plenty of flower without asking for the space or support that taller dahlias often need.
Choose a generously sized pot with good drainage, fill it with fertile compost and place it where the plants will receive plenty of sun. Container dahlias are naturally more dependent on regular watering and feeding than those grown in open ground, particularly once they are in full growth and carrying buds. Deadhead regularly and they will continue producing fresh flowers from midsummer into autumn. Many also provide useful stems for cutting, so a patio pot can contribute indoors as well as outside.
Growing dahlia tubers in pots also gives you more freedom to move the planting as the season changes. Group several containers together for a fuller display, repeat one variety along a terrace or combine different flower forms to give a smaller space more depth. When frost approaches, the pots can be moved somewhere protected or the tubers lifted and stored frost free. Replant them in spring and the same containers can begin another season of growth.
